Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BS2BP2BS1

This summary comes from the ClinGen Evidence Repository: The c.304G>A variant has an allele frequency of 0.00188 (0.19%, 58/30,780 alleles) in the South Asian subpopulation of the gnomAD 2.1.1 cohort (BS1; http://gnomad.broadinstitute.org). The variant was observed in the homozygous state in gnomAD 2.1.1 (BP2). The variant has also been observed in >10 individuals without a diagnosis of diffuse gastric cancer, signet ring tumor or lobular breast cancer and whose family histories do not suggest HDGC (BS2; SCV000210895.12; SCV000186827.5). Therefore, this variant meets criteria to be classified as benign. ACMG/AMP criteria applied, as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): BS1, BS2, BP2 .

Genes affected

CDH1 (HGNC:1748): (cadherin 1) This gene encodes a classical cadherin of the cadherin superfamily. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature glycoprotein. This calcium-dependent cell-cell adhesion protein is comprised of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. Mutations in this gene are correlated with gastric, breast, colorectal, thyroid and ovarian cancer. Loss of function of this gene is thought to contribute to cancer progression by increasing proliferation, invasion, and/or metastasis. The ectodomain of this protein mediates bacterial adhesion to mammalian cells and the cytoplasmic domain is required for internalization. This gene is present in a gene cluster with other members of the cadherin family on chromosome 16. [provided by RefSeq, Nov 2015]

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Variant summary: CDH1 c.304G>A (p.Ala102Thr) results in a non-conservative amino acid change located in the Cadherin prodomain (IPR014868) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00023 in 251274 control chromosomes, predominantly at a frequency of 0.0019 within the South Asian subpopulation in the gnomAD database, including 1 homozygotes. The observed variant frequency within South Asian control individuals in the gnomAD database is approximately 67 fold of the estimated maximal expected allele frequency for a pathogenic variant in CDH1 causing Hereditary Diffuse Gastric Cancer phenotype (2.8e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of South Asian origin. c.304G>A has been reported in the literature in individuals undergoing multi gene panel based testing for cancer (example, Mannan_2016, Mehmet Akcay_2020). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Diffuse Gastric Cancer or Lobular Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven clinical diagnostic laboratories and one expert panel (ClinGen CDH1 Variant Curation Expert Panel) have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (likely benign/benign, n=6). Based on the evidence outlined above, the variant was classified as benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Malignant tumor of breast

Department of Pathology and Laboratory Medicine, Sinai Health System

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The CDH1 p.Ala102Thr variant was identified in 1 of 282 proband chromosomes (frequency: 0.004) from individuals or families with breast or ovarian cancer (Mannan 2016). The variant was also identified in dbSNP (ID: rs368492235) as "With Uncertain significance", and in ClinVar (classified as likely benign by Invitae, GeneDx and Integrated Genetics/Laboratory Corporation of America; as uncertain significance by Ambry Genetics and Counsyl). The variant was identified in control databases in 60 of 246028 chromosomes (1 homozygous) at a frequency of 0.0002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 1 of 15302 chromosomes (freq: 0.00007), European in 1 of 111500 chromosomes (freq: 0.000009), and South Asian in 58 of 30780 chromosomes (freq: 0.002); it was not observed in the Other, Latino, Ashkenazi Jewish, East Asian, and Finnish, populations. The p.Ala102 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

The c.304G>A variant has an allele frequency of 0.00188 (0.19%, 58/30,780 alleles) in the South Asian subpopulation of the gnomAD 2.1.1 cohort (BS1; http://gnomad.broadinstitute.org). The variant was observed in the homozygous state in gnomAD 2.1.1 (BP2). The variant has also been observed in >10 individuals without a diagnosis of diffuse gastric cancer, signet ring tumor or lobular breast cancer and whose family histories do not suggest HDGC (BS2; SCV000210895.12; SCV000186827.5). Therefore, this variant meets criteria to be classified as benign.
